java - 无法获取 org.hibernate.persister.entity.SingleTableEntityPersister 的构造函数 - BuldSession 错误

Question

有人知道为什么会这样吗？我正在使用 Hibernate、Mysql、Maven、Spring。我查看了每篇文章，但找不到解决方案。谢谢:)

Answer 1

Caused by: java.lang.NoClassDefFoundError: javassist/util/proxy/MethodFilter

您需要包括 javassist在你的项目中。添加到 pom.xml :

<dependency>
    <groupId>javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.12.1.GA</version>
</dependency>
